Abstract

A system for detecting anomalies in electrical wiring in a truck trailer. The system measures and compares current drawn from the truck tractor with the current drawn by a circuit at a particular trailer component or other location in the trailer wiring. If the two current measurements differ in excess of a predetermined threshold, the system can report a wiring anomaly. The location of the anomaly can then be determined by performing the operation for different trailer components thus testing multiple different branches of the trailer power distribution circuit, and using the results of these tests to determine that an anomaly is present, and possibly the location of the issue. The system may then send a notification to a remote computing device, to the truck tractor, or any combination thereof.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 62 / 772,847, filed November 29, 2018, which is incorporated herein by reference. Background technique [0003] Anomalies in the trailer power distribution circuit are a common cause of recurring operational failures in truck trailers. For example, corrosion in trailer wiring can cause critical trailer components in the trailer to fail, to actuate pneumatically or intermittently at the wrong time, resulting in failure. Additionally, troubleshooting these issues can be a difficult and time-consuming process and can require costly remediation. Replacing potentially involved portions of the trailer power distribution cable typically requires significant downtime as well as substantial labor and material costs. Contents of the invention [0004] A system for detecting anomalies in electrical wiring in a truck trailer is disclosed. In general, t...
